- Move third-party JS into static/vendor/ and add lucide for icons; refine
.gitignore so embedded vendor dirs aren't caught by the Go vendor rule.
- Replace folder/file emojis in the source browser with lucide icons.
- Wrap the header logo and title in a single anchor so the icon is clickable.
- Drop the redundant "Powered by git-pkgs" footer block; add a GitHub repo
link to the About column and bump the ecosystem count from 16+ to 17+.
- Sticky footer pattern: body is min-h-full flex column with main growing to
fill, so the footer sits at the bottom of short pages.
- Hamburger menu under md: search and nav links collapse into a drawer
toggled by a menu button; theme toggle stays visible at both sizes.
